IMPROVEMENT lN COTTON SCRAPERS.

To all whom it may concern:

Be it known thatI, JAMES M. COBB, of Jackson, in the county of Madison, in the State of Tennessee, have invented certain new and useful Improvements in Cotton-Scrapers or Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the construction of the same, reference being bad to the accompanying drawings, making a part of this specification, in which- Figure 1 represents a perspective view of the scraper, taken from the landside thereof. Fig. 2 represents the plow stock as it appears when the mold-board is removed. Fig. 3 represents a vertical cross-section taken through the beam and sole of the plow.

Similar letters of reference, where they occur in the several figures, denote like parts of the plow in all the drawings.

This invention relates more particularly to the frame which supports the mold-board,said frame being so connected with the beam as to be made adjustable thereon to set the point and share of the scraper more to or from the plants that are to be cultivated.

To enable others skilled in the art to make and use my cotton-scraper, I will proceed to describe the same with reference to the drawings.

The handles A and beam 13 of this scraper may be made and united in anyof the usual well-known ways, and may be made of wood.

A cast-iron frame having four sides, a 1) cd, is pivoted by a bolt at e to the under and rear side or end of the, beam, and a screw-bolt, f, passing through a slot in the top portion, a, of said frame and through the beam allows said frame to be adjusted on the beam. The front portiomd, of the frame is rounded and beveled oft, so as to form a seat and support for the mold-board c, which is bolted to it by bolts 2' i, passing through slots in said piece (I, so as to adjust the mold-board thereon. The rear portion, 0, of said frame makes a brace for supporting the under piece, b,.which forms a landside and partiallya sole to the scraper, as also for bracing the top portion, a, which acts as a plate for the beam to rest upon. This frame is more cheaply made of cast-iron; but it may be wrought out, though at greater expense.

The sole proper of the plowis a broad piece of cast or wrought iron, D, having a flange, m, upon it by which it is boltod to the sole-piece b, above described; and instead of casting the frame and sole d in'two pieces and bolting them together, they may be cast in one piece, and thus still further cheapen the construction of theplow; but by making them separate the sole can be removed and the stock used for other attachments. On the bottom of the sole D there is a wedgeshaped projecting rib, n, which runs through the soil, and thus steadies the plow or scraper,whieh .runs close to the row of plants.

. Having thus described the nature and construction of my scraper or cultivator, what I claim therein as new is The construction and arrangement of the frame, sole, and mold-board, when united in the manner and used for the purposes herein represented and described.
